Pricing

We are currently in our private beta phase.
The beta version is offered at no cost in exchange for statistical information.
The software records how many items are created and which functions of the
app are used. This data is sent to Google Analytics to help us improve the app.
The wiki text content of items is not sent anywhere.

We plan to release a commercial version of DenkWerkZeug with even more features.
We will offer discounts for students, teachers, and our beta users.

Privacy & Reliability

The software runs locally on your own Windows, Mac or Linux computer.
Data is stored on your local hard drive only.
The user interface runs in your browser, loading data from a mini web server built into DWZ, from your hard drive.

Each knowledge file is stored as single XML text file in the KGIF format
(specification).
This allows you to retrieve your data even if you stop using DenkWerkZeug.
Do you wish for a particular export format from DenkWerkZeug to your other tool? Tell us

Download the latest beta version (1.6.3, released on 2015-11-11)
of DenkWerkZeug:

On stage (what you can notice):
= All Items: Now sorted alphabetically, ignoring casing.
= Visual Graph:
+ Showing dotted lines into the void to show where the graph continues.But never show more than 9, to avoid dramatic slow-down.
+ Better choice of node patterns used for automatic captions
= Wiki Syntax:
+ For the Mathematician in you: MathJAX is now enabled. All content between two dollars is type-set as a formula.
Try "$$f(x)=x^2$$" in the note of an item.
= Overall:
= DWZ uses less memory.
= Finished naming concept: Multiple items can have the same name. A disambiguation page appears.
Behind the scenes (what you cannot easily see):
= File
= Open: Fix sorting "Unanamed-9" before "Unnamed-20"
= Visual Graph: Pre-processing completely re-written.
= Computer Assisted Thinking
= Rewritten and simplified. Now correct, but slower. Will become faster than before -- in a later release.
- Bugfix: CDS axiom (hasRelated, isSubTypeOf, type_symmetricRelation) => (typeRelation, isSubTypeOf, type_symmetricRelation)
= Other
+ Handle items without content better (They can appear when importing other formats)
+ Internal index handling rewritten

V 1.5.7, released on 2015-08-20

On stage (what you can notice):
= File
= Versions: Show changes by default grouped in days (was minutes before, resulting in a loooong list)
= Import > RDF: Blank nodes are now rendered as "_" in the graph instead of showing their ugly labels
= AutoComplete: Improved search order of results
Behind the scenes (what you cannot easily see):
+ Improved testability of code base
+ Improved consistent usage of entity metadata time stamps (created and last modified dates)
+ When sorting strings, sort casing now as "Aaa, aaa, Bbb, bbb" was "Aaa Bbb aaa bbb" before.
+ Lock files: Better detection if lock was created by same user on same machine, even if config file got deleted in between
+ Improved implementation and consistent usage of Ids
+ Bugfix for text queries with more than one term (used in AutoCompletion and FullTextSearch)

V 1.5.6, released on 2015-08-13

On stage (what you can notice):
= All Items: Rank items by all links (was just incoming)
= OmniBar:
= Fixed button enabling when text is pasted via mouse -- Thanks Matthias M. for noticing and reporting!
= Search: Scoring now includes duplicate elimination; using best scored match only
= Visual Graph:
- Stopped graph re-layout on every window focus/refocus -- Thanks Uwe M. for reporting
+ Auto-widen caption if links have long labels -- Thanks Uwe M. for reporting (It's still not as cool as Uwe want's it, we know)
+ Don't show 2nd level or deeper nodes if only linked via auto-links
= Show less nodes by default
= File
= Import
= Starts now just after selecting import file, one mouse click saved -- Thanks Uwe M. for caring for the details
= RDF import works again (internal issue with file type detection fixed)
= Export: Fixed -- Thanks Nathan B. for reporting
= Item Rendering
- Stop using different font sizes to distinguish items with no text, a lot of text, no links, many links, etc.
+ Use icons everywhere to display the above flags
= Semantic Panel:
= AutoComplete:
= Fix small bug for auto-focusing object field when an existing relation was chosen
= Fix when searching for "AaaBbb" now also finds "Aaabbb" and "aaabbb" as results
Behind the scenes (what you cannot easily see):
= File
= Import:
= More detailed logging
= Fix issues with auto-detect encoding -- thanks Uwe M. for the sample file
= Progress display: Fixed display of HTML tags in file progress messages
= Starting:
= Fixed booting on Fedora Linux 22, open browser (Fedora 20 worked). Thanks Felix W. for reporting with a log file!
= Always show used ports on console at startup
= AutoLinking:
- Stop auto linking to self
+ Detect, find and link to file://-URLs - but they won't open on most browsers for security reasons
= Logging
- Less logging in some places
+ Can set global log level as command line option now
= Inference
+ Experimenting with delaying re-inference for trading speed for precision on large item sets (> 5k items)

V 1.5.5, released on 2015-07-31

On stage (what you can notice):
= Wiki Syntax:
= External link handling changed: Now by default, URLs and email addresses don't create items. They do, when put in
square braces. This change makes opening many external links much quicker.
= CamelCase: Reduced strings considered CamelCase. Now all CamelCase links must start with an uppercase character.
They may contain numbers and underscore, but not too many of them. Note you can always use square braces to force a link.
= Auto-Linking
- If a wiki name is UPPERCASE; auto link from text only if text is also UPPERCASE
+ Updated internal list of known top-level domain names from official IANA list. Now www.bla.foo becomes a link and
www.foo.bla does not. Yes, '.foo' is a top-level domain name now.
= Fixed some bugs when not all multi-word links where found in all cases
= Bugfix for parsing quotes (would sometimes not display first character in rendered HTML)
= Properties: Fixed a bug where adding single-character values would not work
= Style: Line-break overly long URLs in all places
= Import: Show expected file size during load ("Read x MB of y MB")
Behind the scenes (what you cannot see):
= Import:
= Write each progress step right to a log file (was at the end of the import only)
= Report ALL errors during import to the user
= Auto-Linking:
= Performance improvements
= Bug fix: Auto-linking at import time is now complete and correct.
= KGIF: Tolerate reading ill-formed files with no header-element.

V 1.5.4, released on 2015-07-20

On stage (what you can notice):
= Bugfix for Windows (logfiles names did not work) -- Thanks Matthias M. for reporting
Behind the scenes (what you cannot see):
= Improved locking files so that working together via Dropbox, Google Drive, OneDrive, Box etc... will work better
= Improved error reporting for loading files

V 1.5.3, released on 2015-07-17

On stage (what you can notice):
= Stats
+ Added "Types", all things X in (..., has type, X)
+ Fixed table layout for small browser windows -- Thanks Raphael M.
= Versions
+ Added date to new file name -- Thanks Raphael M.
= All Items
+ Fixed number of tags to show
+ Explain ranking of tags -- Thanks Raphael M. for inquiring
= Graph: Moved buttons to the top of graph -- Thanks Raphael M. for suggesting

On stage (what you can notice):
+ Feature: If search has a single result, navigate there directly
= Fix: Search: Disable search button while query is empty
= Fix: Right panel: Disable form submit, when no new target was entered
= Fix: Right panel: Property delete icon now stays in same line
= Fix: Right panel: Improved table column layout
- Style: Removed '?' and 'leaf' indicators

On stage:
+ Simplified entering statements. No relation needs to be specified, "is related to", the most
basic relation, is used as a default. TODO: Change relation type in a statement.
Thanks for discussing this, Matthias M.
